BlackBerry stocks plunged 22 points this afternoon following a quarterly earnings report that was even worse than expected — and it was already expected to be bad, with The Wall Street Journal reporting earlier this week that up to 40 percent of BlackBerry employees would be laid off by the end of the year.

The chart is stunning, not just for the decline in RIM/BlackBerry market share, but for the dramatic rise of Apple and Android market share. I can’t think of another industry where two newcomers to a relatively established market were able to completely upset and then dominate the incumbents in such a short period of time.
